Dŵr Cymru Welsh Water is the sole water and sewerage company for most of Wales, plus parts of Herefordshire and the England-Wales border. It serves around 1.4 million households – roughly 3 million people. If someone you have lost was a Welsh Water customer, you need to notify the company directly – there is no automatic process that does this for you. The good news: Welsh Water has a dedicated bereavement service, and it offers one of the more generous empty-property charge policies among UK water companies.

How to notify Dŵr Cymru Welsh Water
There are two main ways to notify Welsh Water of a bereavement.
By phone: Call 0800 052 0145, Monday to Friday 8am to 6pm, Saturday 9am to 1pm. This is a freephone number. Tell the adviser you are notifying them of a death – if you have the account number to hand it speeds up the call, but Welsh Water can usually locate the account from the deceased’s name and address if you do not have it.
Online form: Welsh Water’s bereavement form is at contact.dwrcymru.com/en/notify-a-bereavement. It asks for the deceased’s account number, name, address, and date of death, and lets you upload a scan or photograph of the death certificate. Once submitted, Welsh Water will be in touch to discuss what happens to the account, which depends on whether the property will remain occupied or is being sold or let.
Via a third-party notification service: Life Ledger and Settld can notify Welsh Water alongside other utilities, banks, and insurers in a single process. Both are free to bereaved families.

Documents and information you will need
Welsh Water’s notification process asks for the following.
| Item | Notes |
|---|---|
| Deceased’s full name | As it appears on the account |
| Property address | The address the account covers |
| Date of death | Used to date the final bill correctly |
| Account number | A 10-digit number found on any recent water bill; the address is usually sufficient if you don’t have it |
| Meter reading and date | If the property has a meter – a timestamped photo of the display is the most reliable record |
| Your name and contact details | As executor, administrator, solicitor, or next of kin |
| Your relationship to the deceased | And whether you are acting as executor or administrator |
| Death certificate | A copy or interim certificate – scan or photograph is accepted through the online form |
| Property status | Whether it will remain occupied or is being sold or let |
You do not need every document ready before you make first contact. Welsh Water will take an initial verbal notification over the phone and follow up for supporting paperwork afterwards. The priority is getting the bereavement flagged on the account so billing is dated correctly from that point.
If you need extra copies of the death certificate, each certified copy costs £12.50 in England and Wales – order through the register office or via gov.uk/order-copy-birth-death-marriage-certificate.
What happens to the account
Like all UK water accounts, a Welsh Water account is tied to the property rather than to the individual customer. What happens next depends on whether the property stays occupied.
If someone is continuing to live at the property
If a spouse, partner, or other household member remains at the address, Welsh Water will close the deceased’s account and open a new one in the continuing occupant’s name. The meter reading from the date of death or notification becomes the closing reading on the old account and the opening reading on the new one. Any credit balance is refunded to the estate; any outstanding balance becomes a debt of the estate.
If the property is empty
This is the situation most executors face. Welsh Water will typically transfer the account into the executor’s name, or hold it against the estate, while the property is dealt with. Charges continue to accrue – metered usage or the standing charge – until the property is sold, let, or the account is formally closed.
The 12-month charge suspension. Where a sole occupier has died and the property is now empty awaiting probate, Welsh Water can temporarily suspend charges for up to 12 months while you wait for the Grant of Probate to sell or let the property. This is one of the most generous empty-property policies among UK water companies – comparable to United Utilities’ allowance, but longer. It is not automatic: you must tell Welsh Water the property is unoccupied and ask about the suspension when you notify them. Source: Dŵr Cymru Welsh Water bereavements page, verified July 2026.
Metered vs unmetered accounts
Metered properties are charged on actual water use. Take a meter reading as close to the date of death as possible – a timestamped photograph is the most reliable approach – and pass it on when you notify Welsh Water. This fixes the point where the deceased’s final bill ends.
Unmetered properties are charged a fixed annual rate regardless of use. If the property will be empty for some time, ask about the charge suspension described above rather than a meter installation, since Welsh Water’s probate provision covers both metered and unmetered accounts.
The final bill and direct debits
Once the account is closed or transferred, Welsh Water issues a final bill. If the account was in credit – common where a direct debit was set above actual usage – the balance is refunded to the estate; ask about this explicitly when you call, as it is not always volunteered.
Do not cancel the direct debit until you have received the final bill and confirmed the balance is settled. Cancelling early means any outstanding amount has to be paid separately. See our guide to what happens to direct debits when someone dies for wider guidance on managing recurring payments after a death.
Outstanding balances on the final bill are a debt of the estate, paid from the estate’s assets before distribution to beneficiaries. Executors are not personally liable for estate debts.
WaterSure Wales: bill cap for eligible customers
WaterSure Wales caps the annual water and sewerage bill for eligible metered customers who would otherwise be charged more than the cap for their actual usage.
To qualify, a household must:
- Have a water meter (or agree to have one fitted)
- Receive a qualifying means-tested benefit or tax credit, and
- Either have three or more children under 19 living at the property (for whom Child Benefit is claimed), or have a household member with a medical condition requiring significantly above-average water use, such as incontinence, home dialysis, or certain skin conditions
The 2026–27 WaterSure Wales cap is:
| Charge | Annual cap |
|---|---|
| Water supply | £229.28 |
| Sewerage | £354.49 |
| Total (water + sewerage) | £583.77 |
WaterSure is personal to the account holder and ends when the account closes on death. A surviving occupant who takes over the property can apply in their own right if they meet the criteria. Welsh Water also runs the HelpU tariff, a separate income-based discount for low-income households, which a continuing occupant may wish to check as an alternative.

Probate and water bills
Probate is not required to close or transfer a Welsh Water account. A water company is a service provider and potential creditor of the estate, not an asset holder, so there is generally no need to prove authority to deal with the account before it is closed.
If there is a credit balance to be refunded to the estate, Welsh Water may ask for evidence of your authority to act – such as a grant of probate or letters of administration – before releasing funds. For routine closures with no refund due, this is rarely necessary.
Where the property is empty and probate is pending, remember to ask specifically about the 12-month charge suspension described above – it exists precisely to bridge the gap while probate is sought.
Water debt is a debt of the estate, settled from estate assets before anything is distributed to beneficiaries. If the estate cannot meet the debt, Welsh Water will write it off; family members who were not joint account holders are not personally liable. For general guidance on the probate process, see gov.uk/applying-for-probate, or our what to do when someone dies guide for the full sequence of notifications to work through.
How long does it take?
Welsh Water typically processes a bereavement notification and issues a final bill within one to three weeks once they have all the required information. The main variables are:
- Whether the property is occupied or empty
- Whether there is a credit or outstanding balance to resolve
- How quickly the death certificate and account details are provided
Keep a note of the date you called or submitted the form, who you spoke to, and any reference number given. This will resolve any confusion quickly if a routine reminder letter arrives while the notification is still being processed internally.
Things to watch out for
The 12-month suspension is not automatic. If the property is empty and probate is pending, you must explicitly ask Welsh Water for the charge suspension when you notify them. If you do not raise it, charges will continue to accrue as normal.
Take a meter reading as soon as possible. If the property is metered, the reading on or close to the date of death fixes where the final bill ends. A timestamped photograph is the most reliable record. Without it, Welsh Water will estimate, which may not reflect actual usage.
Do not cancel the direct debit before the final bill arrives. This is one of the most common mistakes executors make with utility accounts. Wait for confirmation that the balance is zero before cancelling.
Tell Us Once does not cover water companies. The government’s Tell Us Once service notifies HMRC, DWP, DVLA, the Passport Office, and your local council – but not utility companies. You must contact Welsh Water directly, even if you have already used Tell Us Once. Our guide to notifying your water company after a death covers contact details for every UK water supplier.
Welsh Water covers water and wastewater together. One notification handles both services – there is no separate sewerage company to contact for most of Wales.
Some border properties may be served by a different company. A small number of properties near the England-Wales border are served by Severn Trent or Dee Valley Water rather than Welsh Water. If you are unsure which company serves the property, check a recent bill or use our water company lookup guide.
